13 signs of alien life

More than 40,000 Americans have taken out insurance against being abducted by aliens.

“I think they (we) might all be too far away from one another in space and possibly time.”

US scientist Dr Neil deGrasse Tyson

Physicist Simon Foster, from Imperial College London, believes a space probe currently orbiting Jupiter and Saturn has a “good prospect of finding life”.

He said the discovery of alien life forms is on the horizon.

He said: “In the past, when we thought we had discovered aliens previously, it was a new form of star called the pulsar.

“We know hardly anything and when we come up against something we don’t know or doesn’t fit into our current understanding, it is quite nice to say that it could be aliens, whereas a lot of it is just a phenomena that we haven’t discovered.
